DETAILED DESCRIPTION

Referring generally to the figures, a fog generator assembly isconfigured to mix the fog of water vapor with a fragrance or mixture offragrances and distribute the aromatic fog to a user occupied spaceabove a bath. The fog generator assembly may be configured to select anddeliver one fragrance or a mixture of different fragrances in sequence.According to an exemplary embodiment, the fog generator assemblyincludes an aromatic sequence control system configured to facilitatethe operation of the fog generator assembly.

In some embodiments, the fog generator assembly includes a fog tankconfigured to contain a predetermined volume of water. A lower wall ofthe fog tank may be sloped. In some exemplary embodiments, the foggenerator assembly includes a water delivery and metering system. Thewater delivery and metering system may include a continuous drain.

The fog generator assembly is configured to provide an aromatic mist ofwater vapor in a bath or shower environment. In some embodiments, thefog generator assembly is a self-contained unit separate from the bath.According to an exemplary embodiment, the assembly is configured as anassembly that extends substantially upright from a supporting surfacefor the bath. An upper portion of the assembly extends substantiallyhorizontally above the bath so as to distribute an aromatic fog to auser occupied space above a waterline in the bath. Among other benefits,the aromatic fog provides a cooling effect to the user who may otherwisebecome overheated in the bath.

According to an exemplary embodiment, the fog generator assemblyincludes a water vapor generating portion (e.g., a water vaporgenerator), an aromatic dispensing portion (e.g., a fragrance dispenser)fluidly coupled to the water vapor generating portion, and a mixingportion (e.g., a mixing element) fluidly coupled to both the water vaporgenerating portion and the aromatic dispensing portion. The water vaporgenerating portion includes a water delivery and metering system. Thedelivery and metering system is configured to provide and control thelevel of water in an inner cavity. The metering system may include acontinuous drain as well as an overflow drain. In some exemplaryembodiments, the fog generator assembly may include a base and a coverdisposed thereon. The cover may be configured to guide the flow of waterinto and out of an inner cavity of the base. The water vapor generatingportion also includes a plurality of ultrasonic devices configured tovaporize water contained within an inner cavity.

The aromatic dispensing portion is configured to deliver a plurality offragrances to enhance the user's bathing experience. The aromaticdispensing portion may be automatically controlled from a mobilecomputing device (e.g., an internet of things (IoT) device, a mobilephone, a laptop computer, etc.). In other exemplary embodiments, thearomatic dispensing portion may be automatically controlled from a userinterface disposed on the fog generator assembly. In yet other exemplaryembodiments, the aromatic dispensing portion may be controlled from ahandheld remote for the fog generator assembly. The aromatic dispensingportion may be configured to provide multiple fragrances in auser-customized or pre-programmed sequence. The fragrances may begenerated by convective mass transfer of one, or a plurality of,essential oils into a flowing stream of air.

The amount/quantity of aroma and/or fog that is produced may be variedby controlling the flow rate of air (e.g., a fan speed, etc.) and/or bycontrolling one or more of the plurality of ultrasonic devices (e.g., byactivating/deactivating one or more ultrasonic devices and/or varyingthe voltage or operating frequency of one or more ultrasonic devices).Among other benefits, the aromatic dispensing portion does not rely onheaters or other powered equipment to facilitate the release offragrances from the essential oils, as compared to conventional aromaticdispensing devices. The fragrance is introduced into the mixing portionto generate the aromatic fog, which is then distributed into the useroccupied space. Providing the various fragrances in sequence contributesto an enhanced sensory effect as compared to a single scent, which theuser may otherwise become accustomed to after a short period ofexposure. Advantageously, the aromatic dispensing portion is capable ofmixing together different scents from single containers of essentialoils to form an aromatic mixture, thereby significantly increasing thevariety of fragrances that may be delivered.

Another exemplary embodiment relates to a method of operation for a foggenerator assembly. The method includes receiving a control signal froma remote device, activating one or more ultrasonic devices, fans,lights, and a manifold valve member based on the control signal. Themethod includes querying the control signal. The method includesmonitoring the control signal for a shut-down command and a changecommand. The change command may result in the modification of one ormore operating parameters for the fog generator subassembly.

In some exemplary embodiments, the fog generator assembly is part of awhirlpool bathing system that includes a whirlpool bath. The whirlpoolbathing system may further include a whirlpool filtration systemconfigured to filter (e.g., remove) visible particulate from thewhirlpool bath and improve water cleanliness. The filtration system maybe a retrofit filtration system for use in an existing whirlpool baththat was not originally designed to receive a filter. More specifically,the filtration system may be incorporated into an existing suctionfitting of the whirlpool bath used as part of the water recirculationsystem for the whirlpool bath. The filtration system may be concealedfrom a user's view by the suction fitting and/or other parts of the bathor recirculation system. The filtration system includes a removablefilter that allows a user to easily replace the filter once it becomesclogged. These and other advantageous features will become apparent tothose reviewing the present disclosure and figures.

Referring to FIGS. 1-4, a fog generator assembly is illustrated asassembly 10 according to an exemplary embodiment. As shown in FIG. 1,the assembly 10 is disposed alongside a bath 20 (e.g., a whirlpool, tub,etc.) and is a separate fixture from the bath 20. The bath 20 may formpart of a whirlpool bathing system 21. The assembly 10 includes asubstantially vertical support structure, shown as housing 100, coupledto a support surface for the bath 20. In an exemplary embodiment, thesupport surface is a bathroom and/or shower floor. In other exemplaryembodiments, as shown in FIG. 1, the support surface is a pedestal 23(e.g., platform, etc.) for the bath 20. In some embodiments, the bath 20and the pedestal 23 cooperatively form an overflowing bath in whichwater flows over an upper edge of the bath 20, along a perimeter of thebath 20, and falls, via gravity, onto the pedestal 23. The pedestal 23is disposed between the bath and the floor and completely surrounds thebath 20 so that any water flowing over the edge of the bath 20 isreceived on an upper surface of the pedestal 23. The pedestal 23includes a plurality of slats 25 (e.g., rectangular extensions, etc.)that are distributed across the upper surface. The slats 25 are spacedapart from one another forming openings so that water may flow inbetween the slats 25 and into the pedestal 23 (e.g., an interior portionof the pedestal 23). The slats 25 provide a surface for the user to stepon when entering the bath 20 and improve the overall aesthetic of thebath 20. In other embodiments, the design of the water receiving portionof the pedestal 23 may be different (e.g., the shape of the slats 25,the number of slats 25, the spacing of the slats 25 across the uppersurface of the pedestal 23, etc.). The pedestal 23 redirects the flow ofwater received through the openings between slats to a drain or to asuction fitting for recirculation back into the bath 20. In someembodiments, the fog generator assembly 10 forms part of a faucet forthe bath 20 and provides water to the bath 20 in addition to the fogand/or aroma.

As shown in FIGS. 2-3, a height of the assembly 10 may be modified tosuit the requirements of a given space; for example, the height of theassembly 10 may be greater than a height of the bath 20, so as todispense a fog of water vapor into a user occupied space above the bath20 (e.g., a space above a waterline of the bath proximate to where theuser's head may be located). In this position (in the user occupiedspace above the bath 20), the exposed body-parts of the user will be indirect contact with the fog of water vapor, which can, advantageously,provide a cooling effect to the user. Furthermore, dispensing the foginto the user occupied space above the bath 20 may, advantageously,place the fog in proximity to the user's nose and mouth, and therebymore fully expose the user to the pleasant fragrance.

As shown in FIG. 4, the housing 100 includes a mounting member 102coupled to a lower end of the housing 100. The mounting member 102 isconfigured to couple the housing 100 to the support surface. Accordingto an exemplary embodiment, the mounting member 102 is configured as aplate including a plurality of mounting holes 104. The housing 100 isfastened to the support surface using a plurality of mechanicalfasteners such as bolts, screws, or any combination thereof. In otherexemplary embodiments, the housing 100 is coupled directly to thesupport surface. In yet other exemplary embodiments, the housing 100 isdirectly or indirectly coupled to the bath 20.

In the exemplary embodiment show in FIG. 5, the assembly 10 isconfigured to provide an aromatic fog (e.g., a fragrant mist, etc.) ofwater vapor 30 to the user occupied space just above the bath 20 (seealso FIG. 1). As shown in FIGS. 5-6, the assembly 10 includes a foggenerator subassembly 200 configured to produce (e.g., generate, etc.)an aerosolized fog of water vapor and both introduce and mix a fragrancewith the fog. In the exemplary embodiment of FIGS. 5-6, the foggenerator subassembly 200 is received within the housing 100. A verticalportion 202 of the subassembly 200 is received within the verticalsupport structure. A horizontal portion 204 of the subassembly 200 issupported by the housing 100 in between an upper bracket 106 and a lowercover 108, which are illustrated in further detail in FIGS. 7-10 andFIGS. 11-13, respectively. As shown in FIGS. 11-13, the lower cover 108may include a discharge port 110 configured to align with an exit porton the fog generator subassembly 200 (see also FIG. 6).

As shown in FIG. 6, the assembly 10 additionally includes a light source112 configured to illuminate the discharge port 110 (see also FIG. 5)through which the aromatic fog is ejected. As shown in FIGS. 14-16, thelight source 112 may be configured as a light emitting diode (LED)lighting strip, or another compact light source. In an exemplaryembodiment, the light source 112 includes a support channel 114 thatfacilitates mounting of the light source 112 to at least one of thehousing 100 and the fog generator subassembly 200. The LED lightingstrip may be epoxied or otherwise coupled to the support channel 114. Aclip or another suitable fastener may be coupled to a first end and asecond end of the support channel 114. The clip may be configured toremovably couple the light source 112 to at least one of the housing 100and the fog generator subassembly 200. The light source 112 may bedirected through a discharge portion of the fog generator subassembly200, or alternatively through a portion of the housing 100 outside ofthe fog generator subassembly 200. In the exemplary embodiment shown inFIGS. 7-10, the upper bracket 106 includes a forward lip 115 configuredto reflect light from the light source 112 toward the discharge port110. In this manner, light from the light source 112 can be moreuniformly distributed outward from the discharge port 110 and along alength of the discharge port 110, which can, advantageously, appear tothe user as a stream of light passing through the discharge port 110.

Referring to FIG. 5, the fog generator subassembly 200 includes a foggenerating portion 300 (e.g., a water vapor generator), an aromaticdispensing portion 400 (e.g., a fragrance dispenser) fluidly coupled tothe fog generating portion 300, and a mixing portion 500 (e.g., a mixingelement) fluidly coupled to both the fog generating portion 300 and thearomatic dispensing portion 400. According to an exemplary embodiment,the aromatic dispensing portion 400 is also fluidly coupled to a spacesurrounding the assembly 10 (e.g., the surroundings, a space within thebathroom environment, etc.), and the mixing portion 500 is fluidlycoupled to the user occupied space. The assembly 10 includes an airdisplacement device, shown as fan 600, configured to move air througheach portion 300, 400, 500 of the fog generator subassembly 200. In theexemplary embodiment of FIGS. 5-6, the fan 600 is disposed on a housingof the fog generator subassembly 200, shown as fog tank 206, proximateto an intersection between each of the fog generating portion 300,aromatic dispensing portion 400, and mixing portion 500. Air 211 ispulled through the fan 600 from the aromatic dispensing portion 400toward the fog generating and mixing portions 300, 500. Air 211 isreceived from the space surrounding the assembly 10 into the housing 100through an aperture 107 disposed on an upper surface of the housing 100.Air 211 proceeds through one or more chambers 116 where it is exposed toone, or a combination of, aromatic liquids. The fragrance 213 is carriedby air 211 passing through the activated chamber. The fragrance 213moves with the air 211 into a flow control manifold 702 and out throughan upper opening 208 in the fog tank 206 (e.g., an upper opening 208fluidly coupled to both the fog generating portion 300 and the mixingportion 500, etc.). Proximate to the upper opening 208, the fragrance213 is introduced to an aerosolized fog of water vapor 215, which isgenerated in a cavity 212 of the fog generating portion 300. Among otherbenefits, mixing the fragrance 213 with the fog of water vapor 215stimulates multiple user senses (i.e., is multi-sensory) and contributesto an enhanced bathing experience; the fragrance 213 stimulating auser's sense of smell and the fog 215 stimulating both a user's sense ofsight and touch (e.g., a cooling effect provided to the user via awetting of the user's skin, the cooling of the user by a fog of watervapor at a different temperature than the user, etc.). The fragrance 213continues to mix with the water vapor 215 throughout the mixing portion500, from which the aromatic fog is ultimately ejected to the useroccupied space.

In the exemplary embodiment shown in FIGS. 17-19, the aromatic liquidsare provided in the form of essential oils contained within a pluralityof individual wells 109. The essential oils may emit any one of aplurality of different fragrances (e.g., lavender, vanilla, eucalyptus,peppermint, etc.). The wells 109 may be refillable and removable fromthe assembly 10 to facilitate replenishment of oils and/or replacementof damaged wells 109.

An exemplary embodiment of a well support assembly 118 is shown in FIG.6. The well support assembly 118 includes a support shelf 120, a wellsupport 122, and a chamber cover 124. As shown in FIG. 6, the supportshelf 120 is coupled to the lower cover 108 and forms a substantiallyplanar top surface 121 of the assembly 10. Among other benefits, theproximity of the top surface 121 to a user of the bath 20 provides aneasily accessible dry space to support sensitive electronics (e.g., amobile phone, watch, etc.). In the exemplary embodiment shown in FIGS.20-23, each of the one or more chambers 116 is disposed in the supportshelf 120. The chambers 116 are formed as a plurality of recessed areastoward a rear edge of the support shelf 120. As shown in FIGS. 24-27,each of the wells 109 is supported within the chamber 116 by a wellsupport 122 (i.e., an edge of the support shelf 120 that is farthestfrom the bath 20 of FIG. 1) (see also FIG. 17). The well support 122 isconfigured as a substantially rectangular plate with through holes 128disposed at approximately equally spaced intervals along a length of theplate, although other spacing is contemplated. Each of the holes 128 isconfigured to receive one of the wells 109. The wells 109 are supportedby the well support 122 along an upper ledge of the well 109 (see alsoFIGS. 17-19). In the exemplary embodiment of FIGS. 24-27, each chamber116 is configured to accommodate a single well 109 (See also FIG. 17).In other exemplary embodiments, each chamber 116 may be configured toaccommodate multiple wells 109. According to an exemplary embodiment,both the well support 122 and the support shelf 120 may include aperforated portion to allow the air to move freely through the aromaticdispensing portion 400.

As shown in FIG. 5, a chamber 116 containing one or more wells 109 ofthe plurality of wells 109 is fluidly coupled to both the fog generatingand mixing portions 300, 500 by a flow control manifold 702. Accordingto an exemplary embodiment, the flow control manifold 702 is configuredto facilitate the delivery of a fragrance from one or more chambers 116.Each of the one or more chambers 116 is at least partially fluidlyisolated from the other chambers 116 by the chamber cover 124, so as toprevent scents from one well 109 from altering (e.g., contaminating,mixing with, polluting, etc.) the scents from wells 109 in adjacentchambers 116. An exemplary embodiment of the chamber cover 124 is shownin FIGS. 28-31. The chamber cover 124 includes a plurality ofprotrusions 130 that form a partition between adjacent chambers 116. Theprotrusions 130 may, advantageously, engage with the support shelf 120or well support 122 to help to align the chamber cover 124 with therecessed areas of the well support 122. The protrusions 130 also spacethe chamber cover 124 a distance vertically from the top of the wells109 so as to allow space for air to be pulled into the aromaticdispensing portion 400 (see also FIG. 5). In other exemplaryembodiments, the chamber cover 124 is retractable onto an upper surfaceof the wells 109. Utilizing a retractable chamber cover 124 can,advantageously, reduce evaporation from the wells 109 in one or more ofthe chambers 116 during periods of non-use.

FIGS. 32-33 show the fog generator subassembly 200 separated from theassembly 10, according to an exemplary embodiment. As shown in FIGS.32-33, the fog generator subassembly 200 includes a fog tank 206 and aflow control manifold 702 coupled thereto. The fog generator subassembly200 is configured to produce an aerosolized mist of water vapor usingone or more ultrasonic devices 210 (e.g., ultrasonic nebulizers, etc.).As shown in FIGS. 34-35, the fog generator subassembly 200 includes acavity 212 (e.g., reservoir, etc.) defined by an outer wall 214 of thefog tank 206. The cavity 212 is disposed below (i.e., downwardly from)the upper opening 208 of the fog tank 206. The cavity 212 is configuredto hold a volume of liquid within the fog tank 206. As shown in FIGS.34-35, the fog generator subassembly 200 includes a water delivery andmetering system 216 configured to fill the cavity 212 with water as wellas control a height (i.e., a volume) of the water within the cavity 212.In an exemplary embodiment, the water delivery and metering system 216includes a water supply line configured to fluidly couple the cavity 212with a water source (e.g., a household water supply, etc.) and a waterdrain line configured to fluidly couple the cavity 212 with a drain(e.g., a floor drain, a household sewer/waste line, etc.). The supplyand drain lines may be coupled to the fog tank 206 using a water-tightfastening mechanism such as a barbed fitting, a compression tube fittingsuch as a Swagelok fitting, or any combination thereof. The inletfitting may include one or more check valves configured to preventbackflow of water from the fog tank 206 into the water source.

In the exemplary embodiment of FIGS. 34-35, the water delivery andmetering system 216 includes a flow control valve 218 (e.g., a solenoidvalve, etc.) and a fluid level measurement sensor 220 (e.g., a floatsensor, etc.) communicatively coupled thereto. Together, the flowcontrol valve 218 and the level measurement sensor 220 are configured tocontrol the level (e.g., the volume) of water contained within thecavity 212. In an exemplary embodiment, the flow control valve 218 isconfigured to fluidly couple to the cavity 212 to the water supply lineuntil the level of water is just below the level of the upper opening208 of the fog tank 206. Among other benefits, raising the upper opening208 above the waterline prevents liquid water from sealing off the upperopening 208 and/or restricting flow of the fragrance into the cavity 212through the upper opening 208. In an exemplary embodiment, the flowcontrol valve 218 and level measurement sensor 220 may be integrallyformed (e.g., an integral float actuator).

According to the exemplary embodiment of FIGS. 34-35, the water deliveryand metering system 216 is configured to continuously drain water fromthe cavity 212, which can, advantageously, prevent the growth ofbacteria in the cavity 212 and other parts of the fog generatorsubassembly 200 during periods of non-use. According to an exemplaryembodiment, the cavity 212 is at least partially defined by a lower wall222 enclosing the bottom of the cavity 212. The lower wall 222 is formedat an angle to prevent water from pooling or from otherwise beingcaptured (e.g., retained, etc.) within the fog tank 206. As shown inFIGS. 34-35, the drain is disposed at a lowest point (vertically) alongthe lower wall 222. In an exemplary embodiment, the lowest point isdisposed centrally, proximate to a forward wall 224 of the fog tank 206.Note that, in an exemplary embodiment, there are no horizontal surfacesor angled surfaces within the fog tank 206 upon which water couldaccumulate, thereby helping to reduce the chances for bacteria growth.As shown in FIG. 34, the fog tank 206 includes a substantiallyhorizontal portion 204 configured to direct (e.g., channel, guide, etc.)the aromatic fog of water vapor toward the user occupied space. A basewall 228 (i.e. a bottom wall, etc.) of the horizontal portion 204 isangled toward an exit port of the fog tank 206 to ensure anycondensation remaining on the base wall 228 can discharge through theexit port.

As shown in FIGS. 34-35, the fog generator subassembly 200 additionallyincludes a plurality of ultrasonic devices 210 configured to agitate thewater contained within the cavity 212. Each of the ultrasonic devices isdisposed in the fog tank 206 along the lower wall 222. In the embodimentof FIGS. 34-35, the fog generator subassembly 200 includes sixultrasonic devices 210, although more or fewer ultrasonic devices 210may be used in other exemplary embodiments. According to an exemplaryembodiment, the ultrasonic devices 210 take the form of high frequencynebulizers (e.g., 1.65 MHz nebulizers or another suitable oscillatingfrequency). As shown in FIGS. 36-39, the fog tank 206 includes aplurality of countersunk openings 230 disposed in the lower wall 222,each of the countersunk openings 230 is configured to receive acorresponding one of the ultrasonic devices 210 (see also FIG. 35). Inan exemplary embodiment, the ultrasonic devices 210 are coupled to thelower wall 222 of the fog tank 206 using threaded inserts that aremolded, heat set, pressed, or otherwise formed into the lower wall 222.A grommet, O-ring, or another water-tight sealing mechanism may bepressed into a recessed portion of each of the countersunk openings 230to prevent water from leaking from the fog tank 206.

The design of the fog tank 206 described with reference to FIGS. 32-39should not be considered limiting. Many alternatives are possiblewithout departing from the inventive concepts disclosed herein. Forexample, FIGS. 40-42 show a fog tank 250 that utilizes a separate,self-contained ultrasonic fogger device 252 as opposed to individualultrasonic devices (e.g., nebulizers). The fog tank 250 includes ahousing 254 that is formed in two pieces, an upper portion 256 and alower portion 258. During assembly, the self-contained ultrasonic foggerdevice 252 is placed into the lower portion 258 of the housing 254. Thelower portion 258 includes a plurality of standoffs 260 that extendupwardly from a lower wall 262 of the lower portion 258 that engage withthe fogger device 252 to space the fogger device 252 a distance from thelower wall 262 (e.g., to form a gap between the lower wall 262 and thefogger device 252). Among other benefits, the spacing between the foggerdevice 252 and the lower wall 262 allows water to flow freely along thelower wall 262 to a drain 264 disposed in the lower wall 262. Like thefog tank 206 of FIGS. 32-39, the lower wall 262 of the fog tank 250 ofFIGS. 40-42 is sloped (e.g., angled, curved, etc.) toward the drain 264to prevent water from pooling within the housing 254 during periods ofnon-use. The lower portion 258 is ultrasonically welded or otherwisecoupled to the upper portion 256 to provide a water-tight seal between acavity 266 defined by the housing 254 and an environment surrounding thefog tank 250.

According to an exemplary embodiment shown in FIG. 43, the fog generatorsubassembly 200 includes an aromatic sequence control system 700. Thesequence control system 700 includes a flow control manifold 702configured to guide (e.g., direct, channel, etc.) a fragrance (i.e.,fragrant air, etc.) from one or more chambers 116 (see also FIG. 20) inthe support shelf 120 through the upper opening 208 in the fog tank 206(see also FIGS. 32-33). In the exemplary embodiment shown FIGS. 44-47,the flow control manifold 702 is formed from two pieces of material(e.g., plastic, etc.) that are welded, glued, or snapped, or otherwisecoupled together. In other exemplary embodiments, the flow controlmanifold 702 may be formed as a single unitary piece. As shown in FIG.43, a first end 704 of the flow control manifold 702 is coupled to themanifold bracket 706, which is further coupled to the support shelf 120.In the exemplary embodiment shown in FIGS. 48-51, the manifold bracket706 includes a plurality of ports 708 through which air may pass. Themanifold bracket 706 includes additional holes, slots, and retainingfeatures configured to facilitate integration of the various componentsinto the assembly 10 (see also FIGS. 5-6).

Returning to FIGS. 44-47, the first end 704 of the flow control manifold702 includes a plurality of inlet channels, shown as first inlet channel710, second inlet channel 712, and third inlet channel 714. Each of theinlet channels 710, 712, 714 is fluidly coupled to a corresponding oneof the chambers 116 in the support shelf 120. A second end 716 of theflow control manifold 702 is coupled to the fog tank 206 (e.g.,indirectly or directly coupled to the fog tank 206, coupled to the fogtank 206 by a fan adapter bracket, etc.). As shown in FIGS. 44-7, thesecond end 716 of the flow control manifold 702 includes a dischargechannel 718 that is fluidly coupled to the upper opening 208 in the fogtank 206, and correspondingly, the cavity 212.

In the exemplary embodiment of FIGS. 44-47, the channels 710, 712, 714,718 are arranged around a central valve cavity 720. The walls of each ofthe inlet channels 710, 712, 714 define a central axis 722 for each ofthe inlet channels 710, 712, 714. As shown in FIG. 43, the central axes722, 723, 725 are separated from one another by approximately 60°,although the angular spacing between adjacent inlet channels 710, 712,714 may be different in other exemplary embodiments.

The valve cavity 720 is dimensioned to receive a substantiallycylindrical manifold valve member, shown as valve member 724 in theexemplary embodiment of FIGS. 52-54. As shown in FIGS. 52-54, the valvemember 724 is configured as a disk that includes a central wall 726 andan outer wall 728 extending therefrom. The outer wall 728 extends alongan outer perimeter of the central wall 726 in a direction that issubstantially perpendicular to the central wall 726. Together, thecentral wall 726 and the outer wall 728 define a hollow portionconfigured substantially in the shape of a cup. A slot 730 is disposedthrough the outer wall 728 of the valve member 724. As shown in FIG. 43,the slot 730 can be aligned with any one of the inlet channels 710, 712,714. In the exemplary embodiment of FIG. 43, an angular extent of theslot 730 is approximately equal to an angular extent of one of the inletchannels 710, 712, 714.

The valve member 724 is configured to selectively control the flow ofair through each of the chambers 116 in the support shelf 120. The flowof air through any individual chamber 116 is activated by rotating thevalve member 724 such that the slot 730 is at least partially alignedwith the inlet channel 710, 712, 714 that is fluidly coupled to thedesired chamber 116. In the embodiment of FIG. 43, the valve member 724is configured to fluidly couple the third inlet channel 714 with theupper opening 208 of the fog tank 206. In an exemplary embodiment, thevalve member 724 is configured to rotate in approximately 30° incrementsbetween each of the inlet channels 710, 712, 714, although other angularincrements may be used. By way of example, rotating the valve member 724in a counterclockwise direction by approximately 30° from theorientation shown in FIG. 43 at least partially opens the second inletchannel 712, such that air may pass simultaneously through both thesecond inlet channel 712 and the third inlet channel 714. Rotating thevalve member 724 by another 30° (i.e. a total angular rotation ofapproximately 60° from the initial positon shown in FIG. 43) fully opensthe second inlet channel 712 while preventing the flow of air throughthe first inlet channel 710 and third inlet channel 714. In this manner,various combinations of aromatics and aromatic control sequences areachievable.

In the exemplary embodiment of FIG. 43, the aromatic sequence controlsystem 700 includes an actuator, shown as rotary actuator 732. Therotary actuator 732 is coupled to, and supported by, the flow controlmanifold 702. The rotary actuator 732 is rotatably coupled to the valvemember 724 and configured to control a position of the rotary actuator732. The rotary actuator 732 includes an extension member that engageswith the valve member 724 proximate to a primary axis of the valvemember 724. In an exemplary embodiment, the rotary actuator 732 is amulti-position servo actuator.

The control system 700 may additionally include control electronicscommunicatively coupled to the rotary actuator 732, fan 600, ultrasonicdevice 210, and valve member 724. The control system 700 may include aprocessor, memory, and a network communications interface. The networkcommunications interface may be configured, in part, to receive awireless signal (e.g., Bluetooth, WiFi, etc.) from a remote device(e.g., a control device, etc.).

A method 750 of operation for the aromatic sequence control system 700is shown schematically in FIG. 55, according to an exemplary embodiment.The method 750 includes receiving a control signal from a controldevice, at 752. The control device may be one of a variety of differentelectronic devices (e.g., an IoT device, a mobile phone, a laptopcomputer, a handheld remote, etc.). A user may manually select a set ofoperating parameters or create an operating sequence including multipledifferent sets of operating parameters arranged temporally. A user mayselect the desired sequence of fragrances from a software applicationdownloaded to the control device. For example, the user may be promptedto perform initial setup operations to assign fragrances to each chamber116 in the support shelf 120. Alternatively, the control system 700 mayinclude one or more sensors configured to detect the presence of a well109 and/or a quantity of fluid in a well 109.

The user may utilize the software application to create a customizedsequence of fragrances or a duration for each portion of the sequence.The user may additionally include periods where no fragrance isdispensed into the fog of water vapor, which can, advantageously,prevent a user from becoming desensitized to any of the individualfragrances being emitted into the user occupied space. In otherembodiments, the user may include periods where fragrance is introducedwithout the presence of fog. In yet other embodiments, the release offragrance may be coordinated with the activation or deactivation of thefog. For example, the release of different aromas may be linked with theactivation or deactivation of fog such that the occupant of the bath isalerted to the change in fragrance. In some embodiments, the release ofdifferent aromas in the sequence may be linked with other operatingparameters such as the changing of lighting (e.g., color, intensity,etc.). For example, the color of the light may change whenever a newfragrance is released.

In an exemplary embodiment, the software application may also be used toselect a predetermined sequence. The predetermined sequence may beavailable to other users of the software application (e.g., thepredetermined sequence may be saved to the Cloud, etc.). The sequencemay include the ability to control the intensity and/or color of lightemitted by the light source 112 and/or how the light and fog interactwith the fragrance in each part of the sequence. The softwareapplication may also provide the user with the ability to tune orotherwise modify a characteristic of the fog of water vapor (e.g.,particle size, intensity, etc.). For example, the software applicationmay be configured to allow the user to select an intensity of fog, whichmay result in the activation of additional ultrasonic devices 210,alteration of an operating frequency of the ultrasonic devices 210,and/or alteration of a fan speed. Various alternative control schemesare possible through control of the light source 112, the fan 600, theplurality of ultrasonic devices 210, and the valve member 724.

The method 750 of FIG. 55 further includes activating the ultrasonicdevices 210 and the fan 600, at 754. Operation 754 may includeactivating a number of ultrasonic devices 210 and/or an operatingfrequency for the fan 600 and ultrasonic devices 210 based on a firstpart of a predetermined operating sequence. The method 750 furtherincludes repositioning the valve member 724, at 756, to provide a firstfragrance. The method 750 additionally includes querying the controlsignal for changes to one or more operating parameters, at 758. Themethod 750 also includes monitoring the control signal for a shut-downcommand, at 760 (e.g., a command received at the end of a predeterminedoperating sequence that signals various system components to turn-off).If a shut-down command is received (at 762), the ultrasonic devices andthe fan are deactivated. If a shut-down command has not been received,the system 700 is configured to evaluate whether the control signalindicates that the fragrance or aromatic should be changed, at 764(e.g., whether to adjust the operating parameters of the various systemcomponents to match a second set of pre-specified parameters in anoperating sequence, etc.). If the control signal indicates that thefragrance should be changed, the method 750 returns to operation 756 andrepeats. In other embodiments, the method 750 may include additional,fewer, and/or different operations.

The configuration of the aromatic sequence control system 700 andassociated control methods described in the exemplary embodiment ofFIGS. 43 and 55 should not be considered limiting. Various alterationsand substitutions may be made without departing from the inventiveconcepts described herein. For example, in some embodiments the valvemember 724 may be replaced by a series of individual flow control valves(e.g., solenoid valves, etc.) configured to regulate the flow from eachof the chambers 116. In such an embodiment, the number of activechambers 116 is not limited by the geometry of the slot 730 in the valvemember 724.

Referring to FIGS. 56-64, a fog generator assembly 800 is shown,according to another exemplary embodiment. The fog generator assembly800 is similar to the fog generator subassembly 200 described above,with a few differences. The details regarding the fog tank 206,ultrasonic devices 210, fans 600, water supply and metering system 216provided above are applicable to the corresponding elements of the foggenerator assembly 800. Accordingly, these details have been omittedfrom the following description of the various elements of the foggenerator assembly 800 for the sake of efficiency.

In the exemplary embodiment shown in FIGS. 56-61, the fog generatorassembly 800 is configured to provide a fog of water vapor to a useroccupied space. Unlike the assembly 10 of FIGS. 2-3, the fog generatorassembly 800 of FIGS. 56-61 is configured as a portable fog generatorand can, advantageously, be repositioned anywhere within the bathenvironment (i.e., can be repositioned without having to decouple thefog generator assembly 800 from a supporting surface). The fog generatorassembly 800 includes a housing 802 including a base 804 and a cover 806disposed on the base 804. The cover 806 may be removably coupled to thebase 804 using clips, or another suitable mechanical fastener to provideaccess for users/technicians during maintenance events. The base 804includes a cavity 808 configured to contain a volume of water. The foggenerator assembly 800 includes a plurality of ultrasonic devices 210configured to generate an aerosolized mist/fog of water vapor, which isforced from the cavity 808 by a plurality of fans 810 configured to drawair from the surroundings into the cavity 808. In other exemplaryembodiments, the fog generator assembly 800 is coupled to an aromaticdispensing system (e.g., via a duct fluidly coupled to an inlet to thefans 810, etc.). In yet other embodiments, the plurality of ultrasonicdevices 210 may be replaced with one or more separate, self-containedultrasonic fogger devices (e.g., the fogger device 252 of FIG. 41,etc.).

As shown in FIGS. 60-62, the base 804 includes an integrated overflowconfigured to prevent the water level from exceeding a predeterminedthreshold (e.g., a threshold based on a height of an overflow partition812 in the base 804, etc.). The fog generator assembly 800 mayalternatively, or additionally, include a flow control valve and/orlevel measurement sensor to facilitate metering of the water level inthe base 804. As shown in FIG. 63, the base 804 includes a plurality ofopenings 814, each configured to receive a corresponding one of theultrasonic devices 210.

An exemplary embodiment of the cover 806 for the fog generator assembly800 is shown in FIG. 64. The cover 806 includes an inlet port 816configured to receive a supply line from a water source, an outletopening 818, and a fan platform 820 configured to receive and supportthe fans 810. In other exemplary embodiments, the cover 806 furtherincludes a sensor support member configured to receive and support aliquid level measurement sensor.

The fog generator assembly, of which various exemplary embodiments aredisclosed herein, provides several advantages over conventional devices.Among other benefits, the fog generator assembly produces a controllablefog of water vapor to cool a user or otherwise enhance the user'sbathing experience. The fog generator assembly is self-contained andsupported. The fog generator assembly also includes an aromaticdispensing portion, which is remotely controlled and configured toprovide to the user a sequence of fragrances mixed with the fog of watervapor. The sequence of fragrances is controlled automatically and can becustomized based on user preferences. The fog generator assemblyincludes a housing (e.g., a fog tank 206, a base 804, etc.) having astructural design that can help to prevent water from being retainedwithin the fog generator assembly during periods of non-use, which can,advantageously, prevent the growth of mold or bacteria.

In various exemplary embodiments, the fog generator assembly is part ofa whirlpool bathing system 21 that includes a whirlpool bath 20, asshown in FIG. 1. The whirlpool bathing system 21 further includes awhirlpool filtration system configured to remove visible particulateand/or impurities from the bath 20. In particular, the filtration systemis configured to remove particulate from a water recirculation system(not shown) for the bath 20 that is used to pump water to differentareas within the bath (e.g., water jets, etc.). The whirlpool filtrationsystem is removably coupled to the recirculation system. The visibleparticulate may include large debris such as hair, dirt, and otherdebris which would otherwise cause the user to feel as if he/she isbathing in dirty water.

Referring now to FIG. 65, a whirlpool filtration system is shown asfiltration system 900, according to an exemplary embodiment. In someembodiments, the filtration system 900 is disposed on a suction side ofthe recirculation system upstream of a pump of the recirculation system.In other embodiments, the location of the filtration system 900 may bedifferent (e.g., the pressure side of the recirculation systemdownstream of the pump, at least partially within the bath 20, etc.). Inthe exemplary embodiment of FIG. 1, the filtration system 900 isdisposed within the pedestal 23 and is concealed from a user's view bythe pedestal 23. Water entering the pedestal 23 is routed (e.g., viashrouding, funnel structure, etc.) toward an inlet to the filtrationsystem 900.

As shown in FIG. 65, the filtration system 900 includes a filter housing902 and a filter element 904 (e.g., cartridge, etc.) removably coupledto the filter housing 902. The filter housing 902 includes a body 906defining an inlet opening (not shown) on a first side 908 of the filterhousing 902. The opening is sized to minimize the pressure drop acrossthe filtration system 900. For example, the opening may have across-sectional area that is approximately the same as the total flowarea through the filter element 904. The housing 902 also includes anoutlet extension 907 extending outwardly from a forward surface 909 ofthe body 906 in substantially perpendicular orientation relative to theforward surface 909. As shown in FIG. 65, the outlet extension 907 is aflow tube (e.g., fluid conduit, etc.) configured to deliver fluid fromthe filter element 904 to the recirculation system (e.g., the pump,etc.).

As shown in FIG. 65, the body 906 has a rectangular cross-section normalto a flow direction 912 through the body 906. The body 906 defines ahollow cavity 914 configured to receive the filter element 904 therein.The body 906 supports the filter element 904 and prevents movement ofthe filter element 904 relative to the body 906 during normal operation.The filter element 904 is slidably coupled to the body 906. In theexemplary embodiment of FIG. 65, the filter element 904 is receivedwithin a rectangular slot (e.g., opening, etc.) disposed in an upperwall 916 of the body 906. When the filter element 904 is fully insertedinto the body 906, the filter element 904 occludes the opening in thefirst side of the body 906 such that flow passing through the filtersystem 900 must pass through the filter element 904 before leavingthrough the outlet extension 907.

The filter element 904 includes a frame 918 and a filter media 920disposed substantially within the frame 918. Specifically, the filtermedia 920 is disposed within a rectangular opening defined by the frame918 such that the filter media 920 is surrounded by the frame 918. Theframe 918 is configured to support the filter media 920 along aperimeter of the filter media 920 and to prevent deformation of thefilter media 920 under an applied fluid pressure. The filter media 920may be made from a synthetic mesh and may include nylon, polyester,and/or polypropylene. The frame 918 may be made from polyvinylchloride,nylon, and/or another suitable material.

As shown in FIG. 65, the frame 918 includes a tab 922 (e.g., a finger, acatch, etc.) disposed along an upper edge of the frame 918 and extendingin substantially perpendicular orientation relative to the frame 918.The tab 922 is configured to engage with the upper wall 916 of the body906 when the filter element 904 is fully inserted into the body 906.Among other benefits, the tab 922 facilitates removal of the filterelement 904 from the body 906 when the filter media 920 becomescontaminated. In this way, the filter element 904 may be periodicallyremoved from the body 906 to be cleaned (e.g., by rinsing with water,etc.).

The design of the filtration system 900 shown in FIG. 65 should not beconsidered limiting. Many alternatives are possible without departingfrom the inventive concepts disclosed herein. For example, FIGS. 66-68show a retrofit filtration system 1000 that is configured to be receivedwithin an existing suction fitting 1002 of a whirlpool bath (e.g., inthe base and/or lower portion of the whirlpool bath), according to anexemplary embodiment.

As shown in FIGS. 66-68, the retrofit filtration system 1000 includes afilter element 1004 that is configured to fit within the suction fitting1002 without modifying the suction fitting 1002, into a volume formedbetween the suction fitting 1002 and a wall of the bath. The suctionfitting 1002 shown in FIGS. 66-68 includes an insert 1006 and aperforated top plate 1008 that is coupled to the insert 1006. The topplate 1008 engages the insert 1006 near an outer perimeter of the insert1006 and is secured in place using a fastener (e.g., a bolt, screw,etc.) that passes through a central opening in both the top plate 1008and the insert 1006.

As shown in FIGS. 66-68, the filter element 1004 is received within avolume (e.g., space, cavity, etc.) between the insert 1006 and the topplate 1008. The filter element 1004 includes a frame 1012 and a filtermedia 1014 coupled to the frame 1012. The materials for the frame 1012and the filter media 1014 may be the same as or substantially similar tothe frame 918 and the filter media 920 described with reference to FIG.65. As shown in FIGS. 66-68, the filter media 1014 defines a pluralityof pockets 1016 (e.g., four pockets 1016) that extend into openings 1018of the insert 1006. The frame 1012 is coupled to the filter media 1014along a perimeter of each one of the openings 1018, which prevents thefilter media 1014 from being sucked in through the openings 1018 of theinsert 1006. The frame 1012 engages an outer surface of the insert 1006,along a top lip of the insert 1006 and along dividers 1020 between eachopening 1018. In the exemplary embodiment of FIGS. 66-68, any waterpassing through the insert 1006 must first pass through the filterelement 1004. To service the filter element 1004, the top plate 1008 ofthe suction fitting 1002 is removed and the filter element 1004separated from the insert 1006. The suction fitting 1002 may be removedby loosening and/or removing the fastener. In other embodiments, thesuction fitting 1002 may be removably coupled to the bath usingmechanical clips, a snap on cover, or another suitable fasteningelement. The filter element 1004 can then be cleaned and reinstalledinto the suction fitting 1002.

Among other benefits, the filtration systems 900, 1000 of FIGS. 65-68improve a user's bathing experience by preventing any debris orparticulate from continuously recirculating through the bath duringnormal operation. The filtration systems 900, 1000 may be retrofit intoan existing suction fitting of the bath and may be hidden within thesuction fitting to improve the overall aesthetic of the bath.
